Modification of the Transmission of the UH-1B Helicopter Equipped with a 540-Rotor System for Use as a Universal Transmission for Standard UH-1B and UH-1D Helicopters.
Abstract
Separate transmissions for the UH-1B, UH-1B/540, and UH-1D were the supply system. A need existed for the development of a common or universal transmission that could be easily adapted for use in the three helicopters. In view of this need, the aircraft manufacturer submitted Engineering Change Proposal (ECP) UH-1B/D-242. The ECP incorporated a 'nude' transmission concept and was developed for a transmission that had not entered the supply system. The Iroquois Project Manager initiated a study to determine the feasibility of using one of the three production UH-1 transmissions as the basis for a universal transmission. The Project Manager authorized the 10th Aviation Group, Fort Benning, Georgia, to modify a UH-1B/540 transmission for installation on a UH-1D and a UH-1B. The concept of modifying a UH-1B/540 transmission for use in standard UH-1B and UH-1D Helicopters proved worthy of further investigation.
